Where is a good online guide?

[Planeswalker]

To help teach new users about PHP coding? Also is PHP good for having a "tube" website?

[AceInfinity]

There's online PHP documentation easily findable through google. What do you mean by "tube" website?

You can try w3shools. I learned some things from there.

http://www.w3schools.com/php/

http://www.tizag.com/phpT/ is a very good online source for tutorials.

for beginners.. w2schools is the best place.. then Tizag, next the actual site!

php.net has plenty of good examples if you know anything about coding already.

W3schools by the way.
Anyways, I don't recommend that site because it teaches bad coding practices.
